What can prevent heatstroke and cool down

In summer, the weather is very hot. Many people cannot stand the hot weather and will try all kinds of ways to cool down. Because being in high temperature for a long time is also very easy to cause heatstroke. A common way to cool down is to contact cool substances, such as eating some iced fruits or ice cream. So what can prevent heatstroke and cool down?

Heatstroke prevention and cooling down is a way of using food and drinks to reduce heat in hot summer weather. In the summer, the temperature is high and people sweat too much, which reduces the salt content in the body. The osmotic pressure in the body becomes unstable, resulting in heatstroke. Drinking more salt water or salt tea can replenish the lost salt in the body, thereby achieving the effect of preventing heatstroke.

Heatstroke prevention temperature

At what temperature do you need to take precautions against heatstroke? According to research by biologists, in terms of people's reaction to high temperatures, around 30℃ is the temperature that the human body feels best, because at this temperature there is no need for sweat glands to dissipate heat, nor is there a need for clothing to keep warm.

33℃ - sweat glands start to work. After working at this temperature for 2 to 3 hours, the "human body's" air conditioner - sweat glands start to work and dissipate the stored body temperature through slight sweating.

35℃——The heat dissipation mechanism reacts immediately. At this time, the superficial veins dilate, the skin sweats slightly, the heartbeat speeds up, and the blood circulation accelerates. For some elderly and weak people or those with poor heat dissipation, local cooling is necessary. This temperature is also the starting temperature for activating indoor air conditioning.

36℃——Human body’s “self-cooling”, level one alarm temperature. At this temperature, the human body will dissipate heat through the evaporation of sweat and "self-cool". At this time, you must pay attention to supplementing drinks containing salt, vitamins and minerals to prevent electrolyte disorders. Other cooling measures should also be adopted.

38℃——Multiple organs participate in cooling down, level 2 alarm temperature. Once the temperature rises to 38°C, it is difficult for the human body's sweat glands to maintain normal body temperature. Not only do the lungs "gasp" rapidly to exhale heat, but the heart also has to speed up and output 60% more blood than usual to the body surface to participate in heat dissipation. At this time, cooling measures, cardiac medication care and treatment should not be relaxed in the slightest.

39℃——Sweat glands are on the verge of failure, level 3 alarm temperature. The sweat glands are overworked, unable to function and are on the verge of failure, which can create a risk of a sudden heart attack.

40℃——The brain loses sight of one thing while focusing on another, level 4 alarm temperature. The high temperature has reached the vital center, causing people to feel dizzy and unstable when standing. At this time, people must move to a cool place or use air conditioning to cool down.

The above introduces the human body’s response to high temperatures. I hope it can draw your attention to hot weather. If high temperatures occur, you need to take some necessary heatstroke prevention and cooling measures to avoid discomfort caused by high temperatures.
